FutureWarning: split() requires a non-empty pattern match #29
Description
I found this while investigating astropy/astropy#7928 by:
- Un-silencing warnings in
pytest. - Turn warnings into exception (except for
ImportWarningfrom Cython, which I ignored still). - Run tests on
coordinates(saw this inconvolutiontoo).
